Cittahatthisāriputta Sutta

A number of Elders* were talking on the
Abhidhamma in the Migadāya in Isipatana, when
Citta-Hatthisāriputta broke
into their talk. Mahā Kotthita rebuked him, and, on being remonstrated with by
Citta's friends, Mahā Kotthita implied by means of various similes that Citta
was not the wise man they thought him to be, and that he would, without doubt,
return again to the lay life. This prediction proved true, but Citta came back
once more to the Order, and shortly afterwards became an arahant (A.iii.392ff).

*The DA. (ii.378) which refers to this
incident says that the talk took place between
Moggallāna and
Kotthita.
